Phytogenics in poultry nutrition
Phytogenics, also known as phytobiotics, are natural bioactive compounds of botanical origin that are used as alternatives to antibiotic growth promoters (AGPs) and are added to feed to enhance animal performance. Although phytogenics encompass a wide variety of substances of biological origin, formulation, chemical characterization, and purity, they can be classified into four groups: (1) herbs (products obtained from flowering, woody, and nonperennial plants); (2) botanicals (whole or processed parts of a plant, such as roots, leaves, tree bark, and spices); (3) essential oils (hydro-distilled extracts of volatile plant compounds); and (4) oleoresins (anhydrous solvent-based extracts). These plant-derived products do not contain residues, are natural, and are less toxic than synthetic antibiotics or inorganic chemicals. Many are generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) and can be used as feed additives in animal nutrition.

INTRODUCTION Salmonella has been linked to numerous foodborne illnesses from consumption of poultry products. The FoodNet preliminary data for 2016-2019 identified 25,866 infections, 6,164 hospitalizations and 122 deaths due to foodborne illnesses in United States of which Salmonella contribute about 17.1% of total foodborne infections (Tack et al., 2020; Vaddu et al., 2020). They also reported 5 most common Salmonella serotypes in the US - Enteritidis, Typhimurium, Newport,...

1. Introduction The permeability of the intestinal tract controls the uptake of nutrients and the transport of unwanted extracellular substances such as bacteria and xenobiotics, in addition to the non-digested substances. Therefore, gut health plays an essential role in the pathogenesis of various intestinal disorders. The permeability of the intestine is controlled by gut microbiota, digestive secretions, physical barriers (mucin, intestinal epithelial cells lining and tight...

Introduction Due to increases in population, income and living standards, consumers’ demand shifts to higher quality, various, and more poultry meat consumption. The poultry industry is presently studying on alternatives to meet these consumers’ demands. Also, scientists are trying much more efforts to respond to these expectations. On the other hand, they want to make sure this does not decrease the quality...

About 50-70% of all antibacterial agents used in broiler production are applied to reduce bacterial intestinal infections (bacterial enteritis). Properly conducted prophylaxis and appropriate follow-up can be effective methods of reducing the amount of antibiotics that are used in poultry production. Impaired feed digestion and nutrient absorption lead to the development of indigestion and diarrhoea in poultry. These diseases, apart from subclinical coccidiosis, have the...

Although the first mentions to “choline” date from XIX century (In 1850, Theodore Gobley already described a substance “lecithin”, and then, in 1862, Adolph Strecker heated lecithin from bile, which generated a new nitrogenous chemical termed “choline”), choline’s role nutrition was not well known until 1930s. Since then, several researches have established it as an essential nutrient, which main functions could be summarized...

In the past few years, the concept of “gut health” has established itself as a norm in the scientific literature and animal production. Although the term “gut health” is not specially well-defined, scientists are in agreement that it refers to the capacity of the gastrointestinal tract (GIT) to carry out normal physiological processes and to maintain homeostasis, thereby enabling it to withstand both infectious and non-infectious stressors. It is believed that...

Physiological aspects of the properly functioning digestive system and the organs directly related to it are at the heart of profitability in commercial poultry production. One of the most important organs in the body of every bird is the liver, and the complexity of functions it fulfills proves its unique significance. This organ may be particularly vulnerable to damaging factors, which in turn can contribute to the reduction of production capacity of the flock and, in extreme cases,...

INTRODUCTION Avian coccidiosis is caused by protozoa of genus Eimeria, which belongs to family Eimeriidae and has multiple species with complex life cycle stages (Abbas et al., 2015, 2019; Khater et al., 2020). Eimeria species mostly affect bird intestines and cause bloody diarrhea, poor feed conversion ratios, and high mortality. Among all Eimeria species, E. tenella and E. necatrix are the most pathogenic, causing high mortality in chickens. Naturally, coccidian oocysts are...

Plants extracts (PE) have shown promising effects on performance and intestinal health in broilers. Their potential as antimicrobial (AM) alternatives has been studied for years (Adhikari et al., 2020). A feeding study was conducted to examine the effect of a micro-encapsulated product composed of eugenol and garlic tincture on growth performance, mortality, intestinal lesions, jejunal gene expressions, and histology in broilers during the onset of necrotic enteritis (NE). A total of 960...

I. INTRODUCTION Spotty Liver Disease (SLD) is characterised by increased mortality, particularly around the time of peak egg production, the occurrence of multiple grey/white lesions in the liver, and reduction in egg output. It is caused by Campylobacter hepaticus (Van et al., 2016), which responds to therapeutic antibiotics, although resistance has been reported (Grimes and Reece, 2011). In this study, the ability of a feed-additive containing a standardised blend of...
